XSD came into being after "Namespaces in XML" [1] and is designed
around documents that conform to it. In XML documents that conform to
Namespaces in XML, all tokens that match the Name production in XML
1.0 must also match the NCName production. In effect, this limits IDs
to being NCNames rather than Names.
